Leave a reply

Hurricane Polo hit Sonora on Tuesday morning after crossing the southern part of Baja California on Monday night.

At 8:00 a.m. EDT on Tuesday the center of Hurricane Polo was located at latitude 26.9°N and longitude 111.7°W which put the center about 90 miles (145 km) south-southwest of Guaymas, Mexico.  Polo was moving toward the northeast at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 981 mb.

A large upper level trough over the western U.S. was producing strong southwesterly winds that were blowing toward the top of Hurricane Polo.  Those winds were causing strong vertical wind shear.  Those winds were also blowing the upper part of Polo’s circulation to the northeast of the lower level circulation.  The upper part of Hurricane Polo was already over Sonora.  The lower part of Polo’s circulation was near the coast south of Guaymas.

Hurricane force winds extended out 30 miles (50 km) from the center of the surface circulation around Hurricane Polo.  Tropical storm force winds extended out 90 miles from the center of the surface circulation.

The upper level trough over the western U.S. will steer Hurricane Polo toward the northeast during the next 24 hours.  On its anticipated track, Hurricane Polo will move across northern Mexico toward New Mexico.

The strong vertical wind shear and the mountains in northern Mexico will cause the surface circulation around Hurricane Polo to weaken quickly.  The upper part of Hurricane Polo could reach southern New Mexico on Tuesday night.

Hurricane Polo will continue to produce strong winds and heavy rain over Sonora during the next few hours.  Heavy rain will cause flash floods in some locations.

Hurricane Polo could also drop locally heavy rain over parts of northern Mexico and New Mexico.

Flood Watches are in effect for much of New Mexico.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Rachel was gradually getting better organized.

At 8:00 a.m. EDT on Tuesday the center of Tropical Storm Rachel was located at latitude 15.1°N and longitude 104.8°W which put the center about 370 miles (595 km) south of Cabo Corrientes, Mexico.   Rachel was moving toward the west-northwest at 13 m.p.h. (21 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 992 mb.

Hurricane Polo was still a major hurricane on Monday night.  Winds to hurricane force extended out 40 miles (65 km) from the center of Polo’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Hurricane Polo.

he Hurricane Intensify Index (HII) for Hurricane Polo is 20.6.  The Hurricane Size Index (HSI) is 13.3 and the Hurricane Wind Intensity Size Index (HWISI) is 33.9.  Hurricane Polo is similar in size and intensity to Hurricane Zeta when Zeta hit Louisiana in 2020.

An upper level trough over the western U.S. will steer Hurricane Polo toward the northeast during the next 24 hours.  On its anticipate track, the center of Hurricane Polo will move across the southern part of Baja California during the next few hours.  The center of Polo’s circulation could pass between Loreto and Santa Rosalia.

Hurricane Polo will bring strong winds and heavy rain to southern Baja California. Heavy rain is likely to cause flash floods in some locations.  Hurricane Polo will be capable of causing major damage.

Hurricane Polo will weaken as it moves across the southern part of Baja California.  However, Polo could still be a hurricane when it reaches the west coast of Mexico.  The center of Hurricane Polo will make a landfall on the west coast of Mexico near Guaymas early on Tuesday.

Hurricane Polo will also bring strong winds and locally heavy rain to parts of Sonora.  Heavy rain is likely to cause flash floods in some locations there as well.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Rachel was strengthening gradually.

At 11:00 p.m. EDT on Monday the center of Tropical Storm Rachel was located at latitude 14.3°N and longitude 102.5°W which put the center about 345 miles (555 km) south-southeast of Manzanillo, Mexico.   Rachel was moving toward the west-northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 997 mb.

Hurricane Polo was still a major hurricane on Sunday evening.  A circular eye with a diameter of 17 miles (28 km) was present at the center of Polo’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Hurricane Polo.  Storms near the center of Polo generated upper level divergence that pumped mass away from the hurricane.  The removal of mass in the upper levels was nearly equal to the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure did not change much on Sunday.

The distribution of wind speeds in Hurricane Polo was fairly symmetrical.  Winds to hurricane force extended out 45 miles (75 km) from the center of Polo’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Hurricane Polo.

The Hurricane Intensify Index (HII) for Hurricane Polo is 23.4. The Hurricane Size Index (HSI) is 14.6 and the Hurricane Wind Intensity Size Index (HWISI) is 38.0.  Hurricane Polo is similar in size and intensity to Hurricane Milton when Milton hit Florida in 2024.

Hurricane Polo will move through an environment that will be unfavorable for intensification during the next 24 hours.  Polo will move over water where the Sea Surface Temperatures are near 28°C.  However, Polo will move under the southern part of an upper level trough that is near the West Coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Polo’s circulation.  Those winds will cause the vertical wind shear to increase on Monday.  Hurricane Polo will weaken during the next 24 hours because of more vertical wind shear.

The upper level trough near the West Coast of the U.S. will pull Hurricane Polo toward the northeast during the next 24 hours.  On its anticipated track, the center of Hurricane Polo will make landfall on the coast of southwest Baja California north of Cabo San Lazaro on Monday afternoon.

Hurricane Polo will bring strong winds and heavy rain to southern Baja California. Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Rachel formed south of Mexico.

At 11:00 p.m. EDT on Sunday the center of Tropical Storm Rachel was located at latitude 12.9°N and longitude 99.8°W which put the center about 275 miles (445 km) south-southwest of Acapulco, Mexico.  Rachel was moving toward the west at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1003 mb.

Polo Prompts Hurricane Warning for Baja California

Leave a reply

A risk posed by Hurricane Polo prompted the government of Mexico to issue a Hurricane Warning for a portion of the west coast of Baja California on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Hurricane Polo was located at latitude 19.3°N and longitude 113.1°W which put the center about 325 miles (520 km) southwest of Cabo San Lucas, Mexico.  Polo was moving toward the northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (225 km/h).  The minimum surface pressure was 949 mb.

Hurricane Polo weakened steadily on Saturday, but Polo was still a major hurricane on Saturday evening.  A circular eye was still present at the center of Polo’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Hurricane Polo.  Storms near the center of Polo generated upper level divergence that pumped mass away from the hurricane.  The removal of more mass in the upper levels was less than the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure increased on Saturday.

The size of the circulation around Hurricane Polo increased on Saturday.  Winds to hurricane force extended out 40 miles (65 km) from the center of Polo’s circulation.  Winds to tropical storm force extended out 160 miles (260 km) from the center of Hurricane Polo.

The Hurricane Intensify Index (HII) for Hurricane Polo is 22.1. The Hurricane Size Index (HSI) is 14.9 and the Hurricane Wind Intensity Size Index (HWISI) is 37.0.  Hurricane Polo is similar in size and intensity to Hurricane Milton when Milton hit Florida in 2024.

Hurricane Polo will move through an environment that will be unfavorable for intensification during the next 24 hours.  Polo will move over water where the Sea Surface Temperatures are near 28°C.  However, Polo will move under the southeastern part of an upper level trough that is near the West Coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Polo’s circulation.  Those winds will cause the vertical wind shear to increase.  Hurricane Polo will continue to weaken on Sunday because of more vertical wind shear.

Hurricane Polo will move around the western part of a high pressure system that is over Mexico.  The high pressure system will steer Polo toward the north during the next 24 hours.  The upper level trough that is near the West Coast of the U.S. will steer Polo toward the northeast on Monday.  Polo will reach southern Baja California on Monday.

Hurricane Polo will bring strong winds and heavy rain to southern Baja California.  Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, the upper level trough near the West Coast of the U.S. caused Hurricane Odalys to weaken on Saturday.  At 11:00 p.m. EDT on Saturday the center of Hurricane Odalys was located at latitude 21.1°N and longitude 123.6°W which put the center about 885 miles (1425 km) west of the the southern tip of Baja California.  Odalys was moving toward the north at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 979 mb.

Hilary Rapidly Intensifies to a Major Hurricane

Hurricane Hilary rapidly intensified to a major hurricane over the Eastern North Pacific Ocean on Thursday evening. At 11:00 p.m. EDT on Thursday the center of Hurricane Hilary was located at latitude 16.7°N and longitude 110.0°W which put it about 430 miles (690 km) south of Cabo San Lucas, Mexico. Hilary was moving toward the west-northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 952 mb.

A Hurricane Watch was in effect for the portion of the coast from Punta Eugenia to Punta Abreojos, Mexico. A Tropical Storm Warning was in effect for the portion of the coast from Cabo San Lazaro to Los Barriles, Mexico. The Tropical Storm Warning included Cabo San Lucas. Tropical Storm Watches were in effect for the portions of the coast from Cabo San Lazaro to Punta Eugenia, Mexico and from Los Barriles to Bahia San Juan Bautista, Mexico.

Hurricane Hilary rapidly intensified to a major hurricane on Thursday. An eye with a diameter of 23 miles (37 km) was at the center of Hilary’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Hilary. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Hilary was large. Winds to hurricane force extended out 60 miles (95 km) from the center of Hilary’s circulation. Winds to tropical storm force extended out 290 miles (465 km) from the center of circulation. The Hurricane Intensity Index (HII) was 23.6. The Hurricane Size Index (HSI) was 20.3 and the Hurricane Wind Intensity Size Index (HWISI) was 43.9.

Hurricane Hilary will move through an environment favorable for intensification during the next 24 hours. Hilary will move over water where the Sea Surface Temperatures are near 30°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Hilary is likely to continue to intensify during the next 24 hours. Hilary could intensify rapidly at times on Friday.

Hurricane Hilary will move around the western part of a high pressure system over Mexico. The high pressure system will steer Hilary toward the northwest during the next 24 hours. On its anticipated track Hurricane Hilary will move toward Baja California. Hilary will move more toward the north when it reaches the western end of the high pressure system during the weekend. Hurricane Hilary will start to affect Baja California during the weekend.

Elsewhere, former Tropical Storm Greg and former Tropical Storm Fernanda both weakened to tropical depressions.
